(01.- ne -'37) a invention relates to an incubatorand has ior its primary object to provide a structure; of this character, wherein vapor is produced from water. about a circulating:tube-interiorly thereof andsuch vapor is devoid of a fixed or determined s iont int rio Oi ,the structure is heated and the. temperature maintained uniformlythroughout the interior being, necessary to embryo development within the eggs as placed-withintheincubator. I

. Another'object of the invention isthe provision of an-incubator of this character, wherein the temperature interiorly thereof is automatically controlledywhile eggs to be-hatche'd .are held within trays, these being supported in. racks susceptible, of adj ustmentv from withoutthe-body of the, incubator, while locatedewithin isa water container and aheater. The heater is susceptible of adjustment to vary the temperature and in the working thereof a vaporqusatmosphere is createdwwithin the, said incubator-while the top of-uthelatter is provided with a ventilator, being,likewiseadjustable. V

,gzAgiurther object, of the-invention ;is the prof vision of. an incubator of this character, wherein the;constructionthereof is novel in form-andis of :a-character to enableegg hatchingto be care ried f orthj as an industrial enterprise, there being acertain path for air to travel and a forced draft interiorly ofthe incubator while a. vaporous at. mosphere is present therein andthe temperature of such atmosphere; is automatically controlled. A: still. further object ofthe: invention is the provision of'san incubator ofthis character-which is comparatively, simple in construction-,; thor- :oughly reliableland efficient inits working, readily-1 and easily accessible, assuring embryo-devel-i opment within the eggs stored" therein for the hatchingof the same, strong, durable, and inexpensiveto manufacture.- v V In the accompanying drawingszt Figure l' is a front elevation of an incubator constructed in accordance with the invention.
